I have a chance to get a 30g Oceanic Cube with all the bells and whistles at a great price. I know that Oceanic tanks typically use thicker glass. With that being said, is the glass thick enough to house a 5" and growing peacock mantis? I am not a big fan of acrylic tanks, and the price of a 29-30g Sea Clear is about 2/3 of what the 30g cube complete would be costing me. Thanks
